Imo the first drop was really crummy, had a boring ass buildup then out of nowhere it just dropped.
The fadeout-Sub Focus transition needs a lot of work, try bring the song in during a break rather than using an added effect unless it perfectly slots into the other song.

Sorry if it sounds like a lot of criticism but practice makes perfect! What program you using?

yeah i think you need to work on building the track you want to mix in before it drops, they come out of nowhere and it's a bit disconcerting. that first mix would have worked well i think with the 1 n 2 vocals in the background so try working on more of a smooth transition for each blend and you'll be well on your way
